VLAN trunking

[operations1997]

Hi there,

We are new to VLANs and have 6 switches which we are looking to trunk VLANs between 4 SG300-28PP and 2 SG300-48PP switches.

We are currently trying to get VLANs working with 2 VLANs to start with but after that would like to be able to do more. 

1 - Corporate

8 - Guest

On one of the SG300-48PP switches we have 6 ports assigned to VLAN8 and they are correctly talking to each other.  

The switches are linked by Fibre through the link ports on each switch. 

Can someone please advise on the best way to configure this.

Thank you.

Best way to do this is by creating a VTP domain - select one switch as the server and make the rest clients, create all your VLAN's on the server and then plumb them out as you see fit. Trunk where you need to, and create access ports where you need to

Hi there,

Thank you for getting back to me.  From what I can see VTP is only supported on Catalyst switches which ours are not.

The best way the carry all vlan traffic will be defining a trunk port on switches. 

 for example:

                        vlan 1 ports Gi 1- 8 

                       vlan corpoarate or vlan 2 ports Gi 9 - 15

                       vlan guest or vlan 8    ports Gi 16 - 20

    defining a trunk ports.

    port 24 or may be the fiber ports on switches could be a trunk port. 

    a few parameters there:  

**encapsulation dot1q ( not sure if by default SG300-48PP is using this type of encapsulation )  

** switchport mode trunk and allowed vlans  1, 2, 8 etc.

 if you wants to Inter vlans routing.

 192.168.10.0/24 vlan 1

  192.168.20.0/24 vlan 2

  192.168.30.0/24 vlan 8

  create a subinterfaces in your router 

    int gi 0/0.1 192.168.10. 1  dot1q  1 

    int gi 0/0.2  192.168.20.1  dot1q  2 

   int gi 0/0.3  192.168.30.1  dot1q 8.

  I hope this help Thanks

You need to create VLAN 1 and VLAN 8 in every switch that needs it.
The ports between the switches needs to be trunk ports with VLAN 1 and 8 allowed.
The access ports needs to be either VLAN1 or VLAN8 depending on your need for those particular ports.

Hi,

Additionally, I would like to add that it's better not to use default VLAN 1 and use different VLAN. Just shutdown VLAN 1.
